Correct, cable is a shared medium that is not even close to symmetric
(due to the technology design as content delivery originally rather
than bidirectional), and additionally is oversold absurdly by the
cable networks in many areas. Its not an insurmountable problem, its a
problem the networks are trying to postpone a solution for while
attempting to maximize short term profit. To top it off they are
increasingly pushing more digital content and hd content which further
stresses the problem; which is again because of a content delivery
design paradigm which is *probably a bad idea* but still the current
focus of future cable networks.
Even so, torrents are still effective for users on those networks when
they are throttled to a low, but constant, and reasonable bandwidth.
Those bits moving do help the overall torrent network health and help
deliver content to others... people just need to keep them moving
slowly! My desktop system, on a fairly badly clogged up cable
network, has seeded over 6 Gb of the F9 Preview Live disks already...
at no more than 20kbps at night and limited to 10kbps during the day.
When people download in bursts and upload in slow and consistent rates
the whole situation is much easier handled by the networks.. and
ultimately the people downloading still get high bandwidth from the
torrent.
Its sad that over 3000 downloads of the i686 Preview Live disk have
occurred through the fedora torrent but only 78 seeds are still
active. If even another 200 users were letting their systems seed at
1kbps it would be so beneficial to everyone.
My IAP would prefer its ADSL2+ users pull it at 1.5 Mbytes/sec and
better off its sponsored mirror. Can the torrent beat that?
It's common here for IAPs to have a local (maybe shared) mirror of
popular stuff. Mine offers Fedora, CentOS, Debian, Ubuntu, opensuse,
some BSDs. And gentoo. It might not be an official mirror, so it's worth
checking with your IAP.
Actually, I pulled the images from a mirror and started the seeds with the data
already. But yes thats something for people to be aware of.
